- routine fsys_syncfs (
- fsys: fsys_t;
- RPT
- wait: int;
- do_children: int);
-
-Synchronize the entire filesystem.
-
-This function has a companion in [[`file_syncfs`|file_syncfs]], which is
-invoked on an arbitrary node instead of the server's control port. Both of
-them are usually implemented in equivalent ways.
-
-# Implementation Examples
-
-Servers that either don't keep any unsynchronized state (or don't have a
-backing store at all) can simply `return 0`. Examples: [[translator/symlink]],
-[[translator/nfs]].
-
-## [[libtrivfs]]
-
-Invoke [[`file_sync`|file_sync]] on the underlying node. Rationale: the
-underlying node represents this filesystem's backend, and once this node is
-synchronized, the whole [[libtrivfs]]-based filesystem is to be considered
-synchronized.
-
-### [[storeio]] / [[streamio]]
-
-Instead of to the underlying node, pass the call through to the backend
-(device).
-
-## [[libnetfs]]
-
-Invoke `netfs_attempt_syncfs`.
-
-## [[libdiskfs]]
-
-Invoke [[`fsys_syncfs`|fsys_syncfs]] on all active children, and invoke
-`diskfs_sync_everything` and `diskfs_set_hypermetadata`.
-
-# Usage Examples
-
-## [[libdiskfs]]
-
-In the implementations of both [[`file_syncfs`|file_syncfs]] and
-[[`fsys_syncfs`|fsys_syncfs]], [[`fsys_syncfs`|fsys_syncfs]] is invoked on all
-active children.
